Just a quick note to say, perhaps ,dreamweaver does a better job of these sitewide checks at development stage, but on a page by page basis perhaps after you have moved to staging server this takes the biscuit.

A must for all web designers and developers. I couldn’t recommend it enough

Did Chris leave anything out?

Well aside from a “create lovely website button using web standard techniques and wake me up when you are finished” button! I think he has it pretty much covered. Perhaps a generate lorum ipsum would have been useful, but with the likes of display line guides and display ruler he really has surpassed himself. Creating Web Standard sites is such a breeze with this extension in your arsenal.
